Diving and EON Steel

I have tried connecting the EON Steel to view dives. Some initial questions.
1 Being British I like to record running and cycling in imperial but dives in metric, would it be possible to set preferred units to activities or am I alone in this?
2 Dives in “CCR” mode don’t detail the gas used, it seems to list all the gases stored in the dive computer so I have six gases on my activity, but I only used one.
3 It would be nice to enter the dive site and possibly the GPS and maybe the ability to store known sites. I suspect this would effectively make a dive app.
